Staging: vt6655-6: potential NULL dereference in hostap_disable_hostapd()

2017-03-03T10:31:14+00:00

commit cb4855b49deb1acce27706ad9509d63c4fe8e988 upstream.

We fixed this to use free_netdev() instead of kfree() but unfortunately
free_netdev() doesn't accept NULL pointers.  Smatch complains about
this, it's not something I discovered through testing.

Fixes: 3030d40b5036 ('staging: vt6655: use free_netdev instead of kfree')
Fixes: 0a438d5b381e ('staging: vt6656: use free_netdev instead of kfree')

vt6655: RFbSetPower fix missing rate RATE_12M

2015-04-09T12:14:10+00:00

commit 40c8790bcb7ac74f3038153cd09310e220c6a1df upstream.

When the driver sets this rate a power of zero value is set causing
data flow stoppage until another rate is tried.

staging: vt6655: Fix Warning on boot handle_irq_event_percpu.

2014-08-19T12:23:39+00:00

commit 6cff1f6ad4c615319c1a146b2aa0af1043c5e9f5 upstream.

WARNING: CPU: 0 PID: 929 at /home/apw/COD/linux/kernel/irq/handle.c:147 handle_irq_event_percpu+0x1d1/0x1e0()
irq 17 handler device_intr+0x0/0xa80 [vt6655_stage] enabled interrupts

Using spin_lock_irqsave appears to fix this.

staging: vt6655: Fix disassociated messages every 10 seconds

2014-08-19T12:23:35+00:00

commit 4aa0abed3a2a11b7d71ad560c1a3e7631c5a31cd upstream.

byReAssocCount is incremented every second resulting in
disassociated message being send every 10 seconds whether
connection or not.

byReAssocCount should only advance while eCommandState
is in WLAN_ASSOCIATE_WAIT

Change existing scope to if condition.

Pull networking changes from David Miller:
 "Noteworthy changes this time around:

   1) Multicast rejoin support for team driver, from Jiri Pirko.

   2) Centralize and simplify TCP RTT measurement handling in order to
      reduce the impact of bad RTO seeding from SYN/ACKs.  Also, when
      both timestamps and local RTT measurements are available prefer
      the later because there are broken middleware devices which
      scramble the timestamp.

      From Yuchung Cheng.

   3) Add TCP_NOTSENT_LOWAT socket option to limit the amount of kernel
      memory consumed to queue up unsend user data.  From Eric Dumazet.

   4) Add a "physical port ID" abstraction for network devices, from
      Jiri Pirko.

   5) Add a "suppress" operation to influence fib_rules lookups, from
      Stefan Tomanek.

   6) Add a networking development FAQ, from Paul Gortmaker.

   7) Extend the information provided by tcp_probe and add ipv6 support,
      from Daniel Borkmann.

   8) Use RCU locking more extensively in openvswitch data paths, from
      Pravin B Shelar.

   9) Add SCTP support to openvswitch, from Joe Stringer.

  10) Add EF10 chip support to SFC driver, from Ben Hutchings.

  11) Add new SYNPROXY netfilter target, from Patrick McHardy.

  12) Compute a rate approximation for sending in TCP sockets, and use
      this to more intelligently coalesce TSO frames.  Furthermore, add
      a new packet scheduler which takes advantage of this estimate when
      available.  From Eric Dumazet.

  13) Allow AF_PACKET fanouts with random selection, from Daniel
      Borkmann.

  14) Add ipv6 support to vxlan driver, from Cong Wang"

staging: vt6655: inherit addr_assign_type along with dev_addr

A device inheriting a random or set address should reflect this in
its addr_assign_type.

staging: vt6655: info leak in ioctl

2013-06-24T22:56:10+00:00

The SCmdLinkStatus struct has a couple holes.  There is one between
->bLink and ->wBSSType, and another between ->abySSID and ->uChannel.

I've added a memset() to initialize the struct to zero.  Since we don't
need to clear abySSID any more so I've removed that memset.  It was
wrong anyway: abySSID has "SSID_MAXLEN + 2" (34) bytes, not
"WLAN_SSID_MAXLEN + 1" (33).
